I gave up on Google Chrome for iOS about a day after it was released. Even though my iPhone is jailbroken and I can bypass iOS’s restrictions to set Chrome as my default browser, I missed Safari. Also, Chrome felt considerably slower than the iPhone’s default browser, and that was because Apple handicaps third-party apps by not allowing them to access the lightning-fast Nitro Javascript engine in iOS.

Does the lack of Nitro in your favorite third-party iOS browsers keep you awake at night? Me neither. But that doesn’t mean it wouldn’t be cool to make an app like Google Chrome just as fast as Mobile Safari. For jailbreakers, there’s a new tweak out that makes it all possible.

Nitrous is an awesome new tweak that’s available now in Cydia for $1. With this tweak installed, the iOS Nitro Javascript engine is unlocked for all third-party apps. Not only does this mean that Google Chrome’s web rendering speeds are no longer hindered, but even built-in browsers get supercharged—Tweetbot’s built-in web browser that opens when you tap a link, for example.

Jeff over at iDB ran some benchmarks, and he seemed really impressed with Nitrous:

Not only do the hard line figures speak volumes for this tweak, but I can actually attest to the fact that the tweak makes Chrome more responsive as well. Pages load faster, and you’ll notice an overall boost in snappiness and response as a result.

Grab Nitrous now on your jailbroken iOS device and see if you notice a difference.
